Now, to be clear, it is my opinion that modest immigration is healthy for society and beneficial for trade, cultural development and so forth. Protectionism as a concept is counter-productive, while free trade and the ability for skilled labor to go where they’re in demand is beneficial for everyone.

Having said that, what Sweden is doing is something completely different. The once homogenous population has been forever altered by a rapid and massive addition of people from vastly different cultures and value-systems.

tl;dr: Protectionism is bad. Sweden should be protectionist and homogenous.

... if the rest of the article is like this I'm not sure of the value of it.
